High vacuum oil purifier, or commonly known as degassifier, is a machine that purifies the insulating oil of high voltage equipment. Degassifier consists of heaters, vacuum pump, centrifuge pump and filters that work together inorder to improve the insulating capability of the HV equipment insulating oil.

The heater is important as this will "cooked" the insulating oil that passes through the degassifier. Through this cooking method, the water and moisture content of the insulating oil will be eliminated. The "cooked oil" will then go through an enclosed chamber. Inside this chamber, the insulating oil will be subjected to vacuum pump and centrifuge pump. The vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum . Therefore, this vaccum pump will remove other gases in the oil that can contribute to low level of insulation like acetylene, hydrogen, ethylene, etc. The centrifuge pump is also operated to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through piping.

The constant stirring of the oil by the centrifuge pump will also make the oil vacuuming more effective. Then, the treated oil will be collected to a basin, where it will be pumped again to a filter. The resulting oil will be transferred to a collecting container where it will be ready to be pumped to the desired equipment. There are two types of degassifier, the off-load degassifier and the on-load degassifier. As the name implies, these degassifiers can be operated to an equipment which is energized (on-load) and de-energized (off-load). Degassifiers can also be used to refill a power transformer. Most of the time, only the heaters are left operational and centrifuge pump, vacuum pump and the filter are bypassed during refilling, especially when new insulating oil is being refilled.

Lubricant in use by physical and chemical effects, as well as the effects of pollution and decay occur, lubricant properties of changes is not well protected internal combustion engine, it needs to be replaced.

(1) by heat and mechanical shear effects: evaporation of light components and theviscosity showed an increase in fuel consumption, mechanical shear viscosity can cause temporary or permanent decline, these are the lubrication change.

(2) oxidation nitrification deterioration: engine oil under conditions of use, or because of heat, air and metal catalytic oxidation, or high-temperature lean-burncases, nitrification occurs, will produce resins and asphaltenes, coke and asphalteneformation . The formation of coke or sludge, resulting in further parts of the corrosion,ring sticking, plug filters.

(3) additive consumption and degradation: the combustion and oxidation will consume the acid detergent, high temperature decomposition and oxidation ofsediments will be loss additives, antiwear additives and dispersants, making loss ofthe internal combustion engine lubricant protection.

(4) the accumulation of contaminants: dust and sand on the road, wear metalparticles can be abrasive to the parts; fleeing into the combustion products, will accelerate the rust, corrosion and sludge generation; not burning oil through thepiston rings into the crank box, will reduce the oil viscosity, additive performanceimpact, destruction of oil film strength, resulting in increased wear and tear; coolantleak caused damage more severe than even the fuel dilution.

Dehydration(Degas)systemThe Double-horizontal vacuum evaporation vessels can enlarge evaporation area efficiently. The heater, being places in the vacuum vessels, becomes an evaporator. Thus the evaporation areas of Double-horizontal vacuum vessels are three times more than of the common vacuum vessel. This innovation can dehydrate and degas effectively and separately. This optimal structure of the dehydration (degas) system enlarge the surface area of oil exposed to the vacuum system and extends the flowing distance of the oil in the vacuum system. Thus there has sufficient time to remove the moisture and gas from the oil by vaporization.

Filtering systemThe filtering materials with variable apertures are made of specialized glass fiber.the sizaes of the filtering fiber and aperture dwindle gradually in the different filtering stages. The impurities with different particulate sizes are filtered step by step.the capability of removing particulate matters is improved greatly by this method.
